Definitions

  • the invention relates to a stirring or dispersing device, in particular adapted for comminuting tablets and / or medicament capsules and for dissolving the comminuted tablets and / or medicament capsules in a liquid, with a container having a mixing chamber, with a rotatable about a rotation axis in the mixing chamber rotor and a transmission element which can be coupled or coupled to a drive for transmitting a drive torque from the drive to the rotor.
  • the invention also relates to a stirring or dispersing arrangement with a drive unit having a drive unit and with at least one stirring or dispersing device which can be coupled or coupled to the drive.
  • Such stirring or dispersing devices and stirring or dispersing arrangements are previously known from practice in various embodiments. They are used, for example, to dissolve medical agents in a liquid. For this purpose, tablets and / or medicament capsules are introduced together with a liquid into the mixing chamber of a container of these stirring or dispersing devices. Then, the tablets and / or drug capsules are crushed by means of a rotor having cutting, and mixed with the liquid and optionally dissolved in the liquid.
  • the object of the invention is therefore to provide a stirring or dispersing device as well as a stirring or dispersing device of the type mentioned above, with which the material to be comminuted or dispersed, in particular tablets and / or medicament capsules, is comminuted with great reliability and at Also needs to dissolve in a liquid.

  • a stirring or dispersing device is proposed in which the rotor has at least one cutting projection directed away from a bottom of the mixing chamber and angled towards the axis of rotation with at least one cutting edge.
  • the stirring or dispersing material in particular tablets and / or medicament capsules, can pass with great reliability into the effective region of the at least one cutting projection rotating about the axis of rotation and be shredded by means of the at least one cutting edge.
  • the gravity acting on the material to be comminuted or dispersed can be exploited.
  • the at least one cutting projection can be arranged on an arm of the rotor and have a defined radial distance to the axis of rotation of the rotor.
  • At least one flow breaker be provided, in particular arranged or formed, on a circumferential wall of the mixing chamber surrounding the axis of rotation, in particular transversely or at right angles to the bottom, that a distance of a first, the bottom facing the end of the flow breaker to the axis of rotation is smaller than a distance of a second, the first end facing away from the end of the flow breaker to the axis of rotation.
  • This at least one flow breaker causes the formation of a trombe which is particularly advantageous for stirring or dispersing in a liquid present in the mixing chamber as soon as the rotor, which is also known as Stirring or dispersing tool can be called, is set in motion.
  • This trombe can advantageously extend down to the rotor owing to the at least one flow breaker, so that dispersing material floating in the liquid, in particular tablets and / or medication capsules, can reach the region of the cutting projection and be comminuted.
  • the special design of the at least one flow breaker on the inner peripheral wall of the mixing chamber allows the formation of the previously described Trombenform even with rotor drive concepts, only a relatively small drive torque can be transmitted to the rotor. Therefore, by means of the at least one flow breaker, an energy requirement of the stirring or dispersing device for reliable comminution and dissolution of stirring or dispersing material can be reduced.

  • the deflection surface has a sloping to the bottom and to the inner peripheral wall of the mixing chamber course. This deflection surface causes a backflow of stirring or dispersing material to be comminuted and liquid in the direction of the rotor. Due to the rotation of the rotor during operation of the stirring or dispersing to be comminuted stirring or dispersing and / or liquid is transported radially from the axis of rotation to the outside to the inner peripheral wall of the mixing chamber.
  • a toroidal material flow may form, which favors a particularly fine comminution of stirred or dispersed material and a particularly rapid solution of the stirring or dispersing material, in particular of the tablets and / or medicament capsules.

  • Circular path in the sense of the present invention can be understood to mean the path on which a point of the at least one cutting projection rotates about the axis of rotation when the rotor rotates, which point has a maximum distance from the axis of rotation of the rotor.
  • Another advantage of the stirring or dispersing device according to the invention can be that relatively little drive energy has to be transferred to the rotor because of its construction in order to be able to achieve the desired stirring or dispersion results.
  • the special design of the at least one flow breaker and its arrangement on the inner peripheral wall of the mixing chamber play a special role for this purpose. They allow the formation of an energetically particularly favorable Trombenströmung that can promote a rapid comminution and, where appropriate, solution of the stirred or Dispersierengutes in the liquid. This even if only a comparatively weak drive is available or a limitation of the permissible torque has to be considered.

Abstract

L'invention vise à optimiser le traitement de produits à agiter ou à mélanger, en particulier de comprimés et/ou de capsules de médicaments, et concerne à cet effet un dispositif d'agitation ou de dispersion (1) ainsi qu'un agencement d'agitation ou de dispersion (36) muni dudit dispositif. Selon l'invention, le dispositif d'agitation ou de dispersion (1) présente dans sa chambre de mélange (3) un rotor (4) entraîné par moteur et présentant au moins une partie saillante de coupe (8) coudée ou pliée vers le haut à partir du fond (7) de la chambre de mélange (3) et présentant au moins un tranchant (10). Au moins un brise-flux (12) est conçu au niveau de la paroi circonférentielle intérieure (11) de la chambre de mélange (3) entourant l'axe de rotation (R) de telle manière qu'il présente une forme s'amincissant à partir de sa première extrémité (12) faisant face au fond (7) en direction de sa seconde extrémité (13) opposée à la première extrémité (12). Entre la paroi circonférentielle intérieure (11) et le fond (7) de la chambre de mélange (3) est par ailleurs ménagée une paroi de renvoi (15) servant à renvoyer le produit et/ou le liquide à traiter par agitation ou dispersion en direction du rotor (4). Le ou les brise-flux (12) sont écartés aussi bien du fond (7) de la chambre de mélange (3) que de la ou des parties saillantes de coupe (8) et du trajet circulaire sur lequel la ou les parties saillantes de coupe (8) peuvent être déplacées autour de l'axe de rotation (R) (voir figure 7).
